SASH-HOLDER.

SPECIFICATION forming part of Letters 4Patent No. 750,469, dated January 26, 1904. Application tiled September 17, 1903. Serial No. 173,609. (No model.)

To @ZZ whom it may concern.-

Beit known that I, WILLIAM LEMKE, a citizen of the United States, residing at Camden, in the county of Camden and State of New Jersey, have invented certain new and useful Improvements in Sash-Holders; and I do declare the following to be a full, clear, and eX- act description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in sash-holders.

The object of the invention is to provide means whereby the sashes of windows may be held at any desired height and which will also prevent rattling or undue movement of the sash in the frame.

A further object is to provide a sash-holder which will be particularly adapted for use in connection with the windows of boats, railway-cars, and the like, but which may be also used in connection with the Windows of buildings to do away with the use of sash weights and cords.

With these and other objects in view the invention consists of certain novel features of construction, combination, and arrangement of parts, as will be more fully described, and particularly pointed out in the appended claims.

In the accompanying drawings, Figure 1 is a front elevation of a window frame and sash, showing the application of the invention. Fig. 2 is an enlarged vertical sectional view of one of the holding devices. Fig. 3 is a horizontal sectional view of the same.

Referring more particularly to the drawings, 1 denotes a sliding window-sash. 2 denotes the frame. These parts may be of any form or construction.

3 denotes guide or supporting rods, which are preferably two in number and arranged at each side of the window-sash and connected at their upper and lower ends to brackets 4, which are secured to the window-frame in any suitable manner.

5 denotes the movable members of the holding devices, each consisting of a hollow cylindrical body 6, closed at its upper end and provided at its lower end with interior screwthreads 7. In said threaded end is screwed a nut 8, having a central vertical bore or opening 9. A similarly-arranged opening 10 is formed in the closed upper end of the cylinder 6, the openings 9 and 10 being in vertical alinement, and through the same is adapted to pass one of the rods 3. The inner walls of the cylinders taper inwardly above the screwthreaded portion of the same, thereby forming a conical-shaped cavity l2. Arranged within said cavity and around each rod 3 is a vspring 16, tends to force the washer 13 up into engagement with the tapering inner wall ot' the cylinder, while the pressure of the two springs is exerted upon the said washer to eX- pand the same against said walls and the rod 3 and frictionally hold the cylinder 6 in engagement therewith, as will be understood..

The cylinders are attached to the window-sash at any suitable point by means of bracketplates 6r", so that when said sash is raised the cylinders are slid up or down upon the rods 3 and are supported thereby at any desired height by reason of the frictional engagement of the elastic washers with said rods. the tension of the springs become weakened or the elastic washer worn from use, so that the frictional engagement of the same with the rods is not suicient to support the sash, the tension of the springs may be increased and greater pressure brought to bear upon the washer, thereby causing a greater lateral eX- pansion of the same and increasing the frictional contact with the rods by screwing the nuts 8 farther up into the cylinders and compressing said springs to a greater extent, which will increase the tension of the same, as will Should IOO be understood. The walls of the conicalshaped cavities of the cylinders bear upon the outer edges of the elastic Washers and also tend to force the inner edges of the same against the rods, due to the weight of the sash to which said cylinders are attached, and against the pressure of the upper or lighter spring, thus the heavier the sash the rmer the frictional engagement of the washer with the rods will be, this weight being equalized to some extent by the stronger spring below the washer, thereby preventing any binding of the parts by too great a pressure upon washers.

From the foregoing description, taken in connection with the accompanying drawings, the construction and operation of the invention will be readily understood without requiring a more extended-explanation.

Various changes in the form, proportion, and the minor details of construction may be resorted to without departing from the principle or sacricing any of the advantages of this invention.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is

l. A sash-holder comprising a rod, a member slidably related thereto and having a tapered bore through which the rod extends, a laterally-expansible friction-clutch member in the bore and on the rod, and movable longitudinally thereof, and yielding means to exert pressure on opposite sides of said laterallyexpansible friction-clutch member.

2. A sash-holder comprising a rod, a member slidably related thereto and having a tapered bore through which the rod extends, a laterally-expansible friction-clutch member in the bore and on the rod, and movable longitudinally thereof, yielding means to exert pressure on opposite sides of said laterallyexpansible friction-clutch member, and means to vary the tension of said pressure-exerting means.

3. In a sash-holder, the combination with a window-frame having supporting-rods fixed thereto, of a sliding sash carrying movable members arranged to engage and slide on said rods, said movable members consisting of hollow cylindrical bodies closed at one end and having open interiorly-threaded opposite ends, nuts or threaded plugs adapted to be screwed into and close said open-threaded ends, a laterally-expansible washer arranged within said hollow cylindrical bodies and around said rods, and means arranged above and below said washer to expand the same and thereby cause africtional engagement thereof with the inner walls of said cylinder and with said rods, substantially as described.

4. In a sash-holder, the combination with a window-frame having supporting-rods fixed thereto, of a sliding sash carrying movable members arranged to engage and slide on said rods, said movable members consisting of hollow cylindrical bodies closed at one end and having open interiorly-threaded opposite ends, nuts or threaded plugs adapted to be screwed into and close said openthreaded ends, a laterally-expansible washer arranged within said hollow cylindrical bodies and around said rods, metallic washers arranged on each side of said expansible washer, springs arranged above and below said washers, the tension of which is exerted to laterally expand said expansible washer, substantially as described.

5. In a sash-holder, the combination with a window-frame having supporting-rods lixed thereto, of a sliding sash carrying movable members arranged to engage and slide on said rods, said movable members consisting of hollow cylindrical bodies closed at one end and having open interiorly-threaded opposite ends, nuts or threaded plugs adapted to be screwed into and close said open threaded ends, a laterally-expansible washer arranged within said hollow cylindrical bodies and around said rods, metallic washers arranged on either side of said expansible washer, a light spring arranged above said washers and a heavy spring arranged below the same, the tension of said springs being exerted to expand said expansible washer, and means whereby the tension of said springs and the expansion of said washer may be increased, substantially as described.

6. In a sash-holder, the combination with a window-frame having supporting-rods fixed thereto, of a sliding sash carrying movable members, said movable members consisting of hollow cylindrical bodies having conicalshaped cavities closed at one end and having open interiorly-threaded opposite ends, nuts or threaded plugs adapted to be screwed into and to close said open threaded ends, alined opening formed in the closed end and nuts of said cylindrical bodies through which pass said supporting-rods, a split, expansible washer arranged within said conical cavities and around said rods, metallic washers arranged on each side of said split washer, a light spring coiled around said rods above said washers and a heavy spring similarly arranged below the same, the tension of said springs being exerted to expand said split washer, and means whereby the tension of said springs and the expansion of said washer may be increased, substantially as described.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

WILLIAM LEMKE.
